Abstract

EIDs have been increasing steadily since at least 1940. For every decade since 1940, there has been a consistent increase in the number of EID events from wildlife-related zoonosis. An emerging infectious disease (EID) is an infectious disease whose incidence has increased recently (in the past 20 years) and could increase in the near future.The minority of diseases that are capable of developing efficient transmission between humans can become major public and global concerns as potential causes of epidemics or emerging infections (EIDs) account for at least 12% of all human pathogens. EIDs can be caused by newly identified microbes, including novel species or strains of virus (e.g., novel coronaviruses, ebolaviruses, HIV).
